Definitions
- the present invention relates to a friction material suitable as a material for a braking member, for example, a material for a clutch facing, a material for a brake, and the like used in a braking device for an automobile, an aircraft, a railway vehicle, and industrial equipment.
- a friction material suitable as a material for a braking member for example, a material for a clutch facing, a material for a brake, and the like used in a braking device for an automobile, an aircraft, a railway vehicle, and industrial equipment.
- a friction material in a braking member a friction material obtained by dispersing asbestos in an organic or inorganic binder and binding and forming the same has been used.
- a friction material using octaluminium titanate fiber or potassium hexatitanate fiber as a base fiber or a friction modifier has been proposed.
- These titanate-reinforced rubber fibers do not have the carcinogenic properties of asbestos, have excellent heat resistance, and are effective in preventing fade phenomena and improving the thermal stability of friction characteristics. I have.
- the present invention has been made in view of the above-mentioned conventional problems, and provides a friction modifier capable of improving friction and wear performance from a completely new viewpoint.
- the friction material of the present invention is characterized in that potassium dititanate and Z or tetratitanic acid reamer are blended as a friction modifier.
- Both dipotassium titanate and potassium tetratitanate used as friction modifiers in the present invention are compounds having a layered structure. It is a completely different compound.
- Potassium titanate having such a layered structure when blended into a friction material, easily causes layer separation under high-temperature friction and sliding, and spreads uniformly on the sliding surface in the form of a film to improve friction and wear characteristics. Having.
- the friction material of the present invention has an excellent effect that the friction coefficient can be kept uniform.
- the friction modifier of the present invention can be separated and diffused in a plate shape in the friction material by mixing with a high shear during the production to form a so-called nanocomposite structure. Further, the friction material of the present invention has excellent strength.
- potassium dititanate and potassium tetratitanate may be in various shapes such as granular, columnar, fibrous, and scaly.
